Internal Crossover Configurations
The crossover section of the Orion XTR5001, XTR10001, and XTR15001
amplifiers is continuously variable and extremely flexible. In addition
to the variable built-in low-pass filters, the high-pass crossover incor-
porates the Bass Boost feature. This circuit is designed to optimize the
performance of Orion subwoofers in all types of enclosures.
When using Orion loudspeakers, minor deviations from the recom-
mended frequency ranges can provide superior results depending on
your speaker locations and your vehicle acoustics. Setting crossover
frequencies higher than recommended will not cause damage and
may provide superior sonic results depending on your system’s perfor-
mance goals. Refer to your loudspeaker owner’s manual for assistance
in choosing the proper crossover frequencies for your system.
WARNING! DO NOT set crossover frequencies lower than the speakers
recommended operating range. This can cause driver failure that is
not covered by the manufacturer’s warranty.
Low-Pass Crossover
When the switch is to the left (Full position), the low-pass crossover is
bypassed. When the switch is in the middle (12 position), the low-pass
crossover is active with a 2nd order (12dB per octave) slope. When the
switch is to the right (24 position), the low-pass crossover is active with
a 4th order (24dB per octave) slope. The low-pass crossover is continu-
ously variable from 30Hz to 250Hz.
Remote Gain Operation
NOTE: Do not use the Remote Gain control when you have an
expanded system installed (see Line Output Configurations). The Slave
amplifier(s) gain will not be controlled.
The remote gain port provides easy remote access to the internal gain
structure of the XTR power amplifier. The RGC2 plugs into the amplifier
via the 1/8” mini jack plug. The RGC2 can be installed in the front of the
vehicle to control the amplifier gain level. The RGC2 can be used as a
bass level control when used on an amplifier dedicated to subwoofers.
